A Rambo-style gunman suspected of killing three Canadian Mounties and wounding two others has been arrested.

Justin Bourque had been on the run after allegedly shooting the officers in a stand-off when they responded to a report of an armed man in Moncton, New Brunswick.

The 24-year-old was arrested at about 12.30am local time as it emerged he told a former colleague ‘he always wanted to go out with a bang’.

Michelle Thibodeau, 21, said she saw a man arrested in the front garden of her home in New Brunswick and heard him say, ‘I’m done’ before he was seized by armed officers.

The arrest came after police released an image believed to be of the 24-year-old armed with two rifles, dressed in camouflage and wearing a bandana, similar to that of the Sylvester Stallone character.

As the city’s lockdown ended, Bourque’s co-worker at Walmart, Caitlin Isaac, said she was ‘surprised, and also not’ that he was suspected of the shootings because he said he wanted to ‘give people something to remember him for’.

She said: ‘I never took him seriously, but he always said he wanted to go out with a bang and bring people with him.

‘He’s always seemed to have a problem with authority. Issues with parents, bosses, police.

‘A few people from work went camping one weekend, and he came, and brought his rifle with him, which he held on to the whole night while drinking. That kind of freaked us out, we didn’t invite him the next time.

‘He has two large guns, a knife, and a bow and arrow with him.’

A Facebook page believed to belong to the suspect contains posts advocating gun rights, even for children and several disparaging posts about the police and politicians.

However, at 3pm yesterday, that account was deleted and reopened with a single picture of the suspect and a shooting buddy surrounded by spent cartridges in the snow.

The two wounded officers were treated in hospital for what were called non-life-threatening injuries.
